The anode is the positive electrode so attracts negative ions. At the anode, negative ions lose electrons (they are oxidised).The resulting product depends on the ionic substance but is non-metal and is o...

The outer shell of electrons in metals are delocalised, meaning they are able to travel freely around the metal.

The negative electrons hold the positively charged metal ions together. The poo...
